I'm not an expert but... isn't WILD pretty advanced technique? I'm into lucid dreaming for few years now and never even tried it yet because I've found it the most difficult. Just try standard WBTB. I found it best when getting up after 5 hours not 6 (because after 6 I've literally started to sleep for like 10 hours everyday which I think is kinda waste of my daytime). Don't forget to do random reality checks during day and start your dream journal. Yes, it's pretty annoying but it will help a lot with dream recall.
